3.13.1. 13-** Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user defined actions (see par. 13-52 [x]) executed by the SLC when the associated user defined
event (see par. 13-51 [x]) is evaluated as TRUE by the SLC. Events and actions are each numbered and linked together in pairs. This means that when
event [0] is fulfilled (attains the value TRUE), action [0] is executed. After this, the conditions of event [1] will be evaluated and if evaluated TRUE,
action [1] will be executed and so on. Only one event will be evaluated at any time. If an event is evaluated as FALSE, nothing happens (in the SLC)
during the current scan interval and no other
events will be evaluated. This means that when the SLC starts, it evaluates event [0] (and only event [0])
each scan interval. Only when
event [0] is evaluated TRUE, will the SLC execute action [0] and start evaluating event [1]. It is possible to programme
from 1 to 20
events and actions .
When the last
event / action has been executed, the sequence starts over again from event [0] / action [0]. The illustration shows an example with three
event / actions:
Starting and stopping the SLC:
Starting and stopping the SLC can be done by selecting
On [1] or Off [0] in par. 13-00. The SLC always starts in state 0 (where it evaluates event [0]).
The SLC starts when the Start Event (defined in par. 13-01
Start Event ) is evaluated as TRUE (provided that On [1] is selected in par. 13-00). The SLC
stops when the
Stop Event (par. 13-02) is TRUE. Par. 13-03 resets all SLC parameters and start programming from scratch.
